    Abstract: An apparatus includes a bank of optical detectors, an input optical filter and a selector. The optical detectors are configured to output respective detection indications in response to detecting a presence of an optical signal. The input optical filter is configured to receive an input optical signal having an input wavelength, and to route the input optical signal to one of the optical detectors in the bank depending on the input wavelength. The selector is configured to select an output wavelength based on the detection indications of the optical detectors, and to cause generation and transmission of an output optical signal at the selected output wavelength.

    Abstract: A method for communication includes producing an error signal by comparing a driving signal applied to a transmitter to an output signal generated by the transmitter in response to the driving signal. The error signal is decomposed into a linear component having a first memory depth and a nonlinear component having one or more polynomial orders and a second memory depth that is less than the first memory depth. First coefficients, up to the first memory depth, of a linear predistortion kernel are computed for application to the driving signal so as to compensate for the linear component of the error signal. Second coefficients for the one or more polynomial orders, up to the second memory depth, of a nonlinear predistortion kernel are computed so as to compensate for the nonlinear component of the error signal. Operation of the transmitter is optimized using the first and second coefficients.

    Abstract: An method for characterizing a modulator for fabricating a silicon photonics circuit and an apparatus (e.g., a silicon photonics wafer) made via the method are described. The method includes determining an absorption spectrum of a modulator and determining, based at least on the determined absorption spectrum, an operational bandwidth of the modulator. The method further includes selecting a laser for coupling with the modulator using the operational bandwidth of the modulator. In this way, the laser is selected such that it has an emission bandwidth that corresponds to the operational bandwidth of the modulator.

    Abstract: An apparatus includes an array of electro-optical transducers, control circuitry, and a connector housing. The electro-optical transducers are configured to convert between electrical signals and respective optical signals conveyed over respective optical fibers. The control circuitry is configured, in response to a failure of a first electro-optical transducer in the array that is associated with a given optical fiber, to switch one or more of the electrical signals and the optical signals so as to replace the first electro-optical transducer with a second electro-optical transducer in the array in conveying an optical signal over the given optical fiber. The connector housing contains the array of the electro-optical transducers and the control circuitry.

    Abstract: An apparatus for interconnecting devices in a network comprises a connection interface with a first face and a second face opposite the first face. The apparatus includes a first 2D array of first connection points arranged on the first face of the connection interface. Each first connection point in each column of the first 2D array connects to a different host device from among a plurality of host devices, and each first connection point in each row of the first 2D array connects to a single host device from among the plurality of host devices. A second 2D array of second connection points is arranged on the second face of the connection interface. Each second connection point is connected to a respective first connection point, each second connection point in each column of the second 2D array connects to a single network switch from among a plurality of network switches, and each second connection point in each row of the second 2D array connects to a different network switch from among the plurality of network switches.
